The capability of plugging these detectors into a variety of special bases makes them more versatile than equivalent direct-wired models. Refer to the System Sensor catalog for other available plug-in detector bases. Before Installing Please thoroughly read the System Sensor manual I56-407, Guide for Proper Use of System Smoke Detectors, which provides detailed information on detector spacing, placement, zoning, wiring, and special applications. Copies of this manual are available at no charge from System Sensor. (For installations in Canada, please refer to CAN4-S524, Standard for the Installation of Fire Alarm Systems, and CEC Part 1, Sec. 32.) This base is intended for use in 2-wire systems, with screw terminals provided for power, ground, and remote annunciator connections. The base also contains a resistor to provide current limiting in the alarm state. NOTICE: This manual should be left with the owner/user of this equipment. IMPORTANT: The detector used with this base must be tested and maintained regularly following NFPA 72 requirements. The detector used with this base should be cleaned at least once a year. D150-04-00 1 I56-596-03R Figure 1. Mounting base to box: Mounting This detector base mounts directly to 3-1/2- inch and 4inch octagon boxes, and 4-inch square boxes (with or without plaster rings). To mount, remove decorative ring by turning it in either direction to unhook the snaps, then separate the ring from the base. Install the base to the box using the screws supplied with the junction box and the appropriate mounting slots in the base. Place decorative ring onto base, then turn in either direction until the ring snaps in place (see Figure 1). SNAP ON DECORATIVE RING Installation Guidelines All wiring must be installed in compliance with the National Electrical Code and the local codes having jurisdiction. Proper wire gauges should be used. The conductors used to connect smoke detectors to control panels and accessory devices should be color-coded to reduce the likelihood of wiring errors. Improper connections can prevent a system from responding properly in the event of a fire. SCREWS (NOT SUPPLIED) SHORTING SPRING For signal wiring (the wiring between interconnected detectors), it is recommended that the wire be no smaller than 18 gauge (1.0 square mm). Wire sizes up to 12 gauge wire (2.5 square mm) may be used with the base. For best system performance, the power (+) and (–) loop wires should be twisted pair and installed in separate grounded conduit to protect the loop from extraneous electrical interference. DETECTOR BASE BOX (NOT SUPPLIED) Smoke detectors and alarm system control panels have specifications for allowable loop resistance. Consult the control panel manufacturer’s specifications for the total loop resistance allowed for the particular model control panel being used before wiring the detector loops. A78-1175-01 CAUTION For system supervision — For terminals 2, 3, and 5 do not use looped wire under terminals. Break wire run to provide system supervision of connections. Wire connections are made by simply stripping insulation from the end of the wire, sliding the bare end of the wire under the clamping plate, and tightening the clamping plate screw. Use the strip gauge molded into the base for ease of wiring to terminals 1 through 5. The zone wiring of the detector base should be checked before the detector heads are installed in them. To make this possible, this base contains a special spring-type shorting jumper. After a detector base is properly wired and mounted on an electrical box, make sure that the jumper spring is in contact with the base of Terminal 3. This temporary connection shorts the negative-in and negative-out leads and permits the wiring of the loop to be checked for continuity. System Sensor smoke detectors and mounting bases are marked with a compatibility identifier located as the last digit of a five digit code stamped on the back of the product. Connect detectors/mounting bases only to compatible control units as indicated in System Sensor’s compatibility chart which contains a current list of UL listed control units and detector head/base combinations. A copy of this list is available from System Sensor upon request. D150-04-00 2 I56-596-03R Figure 2. Typical wiring diagram for 2-wire detector systems: + REPEATER PANEL – 2-WIRE CONTROL PANEL – 2 2 3 1 5 3 1 4 5 4 E O L A78-1175-05 + OPTIONAL FAULT TOLERANT WIRING To make the detector tamper-resistant, use needle-nose pliers to break the smaller tab at the scribed line on the tamper- resistance tab. Figure 3A shows the location of this tab on the detector mounting bracket. Once all the detector bases have been wired and mounted, and the loop wiring has been checked, the detector heads may be installed in the bases. The shorting spring in the base will disengage automatically when the detector head is removed from the base. DO NOT remove the shorting spring since it reengages as the detector head is turned into the base, completing the circuit. To remove a detector from the bracket after it has been made tamper resistant, use a small screwdriver or other similar tool, to depress the tamper-resistance tab in the slot on the mounting bracket, and rotate the detector counterclockwise (see Figure 3B). Tamper-resistance Feature NOTE: Do not use the tamper-resistance feature if the XR2 removal tool is to be used. NOTE: The decorative ring must be removed before the smoke detector can be detached from the base after the tamper-resistant capability is enabled. The tamper-resistant tab, in the detector mounting bracket, can make the detector tamper-resistant by making it necessary to use a small screwdriver or similar tool to detach the detector from the bracket.
